Anonymous hackers have compromised the private Gmail account of a low-level White House staffer, and posted the email archive publicly on the site DCLeaks. It’s the same site that published Colin Powell’s personal email archive earlier this month, as well as emails from the Democratic National Committee. A number of analysts believe the site is part of a Russian effort to influence US politics.

The emails deal largely with day-to-day logistics, but also include what appears to be an image of first lady Michelle Obama’s passport. Since the staffer’s duties largely involve travel and other logistics, it’s plausible he would have had access to the passport, although it’s unclear why it was sent through his personal Gmail address.
